Description

Technical Field

[0001] This utility model belongs to the technical field of label spraying equipment, and in particular relates to an automatic spraying device for waterproof coating of outdoor labels. Background Technology

[0002] Outdoor labels are signs used for identification, explanation, or advertising that are exposed to the outdoors for extended periods. Because they must withstand harsh weather conditions such as sun exposure, rain, and temperature fluctuations year-round, their substrate surface typically requires a dense waterproof coating to prevent moisture penetration that could cause deformation, fading, or damage. This ensures a long service life and clear legibility. In the production process of outdoor labels, automated waterproof coating spraying equipment is a key component. It automatically and evenly sprays the coating onto the label surface, significantly improving production efficiency, coating uniformity, and quality stability compared to traditional manual spraying.

[0003] Existing automatic spraying devices for waterproof coating of outdoor labels still have some problems during use. For example, after a batch of labels is sprayed, there will be residual paint on the inner wall of the spraying pipe. If this paint is not cleaned in time, it will quickly solidify and adhere to the pipe wall and nozzle, causing the pipe diameter to decrease or become completely blocked. This will not only seriously affect the uniformity and quality of the next spraying operation, but may even cause the equipment to fail to start normally. The traditional method requires manual disassembly and flushing of the spraying pipe, which is not only cumbersome and time-consuming, but also labor-intensive, resulting in prolonged equipment downtime and affecting overall production efficiency.

[0004] To address this issue, we provide an automated spraying device for waterproof coating of outdoor labels. Utility Model Content

[0005] The purpose of this utility model is to provide an automatic waterproof coating spraying device for outdoor labels. Through the structural cooperation of the rinsing mechanism and the conveying mechanism, it solves the problem that existing automatic waterproof coating spraying devices rely on manual disassembly of the spraying pipe for manual rinsing. This process is not only cumbersome and time-consuming, but also labor-intensive, leading to prolonged equipment downtime and affecting overall production efficiency.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to an automatic waterproof coating spraying device for outdoor labels, comprising a spraying box, a placement plate at the bottom of the spraying box, a moving component at the top of the spraying box, a spraying pipe on one side of the moving component, a material conveying pipe connected to one side of the spraying pipe, a rinsing mechanism on one side of the inside of the spraying box, the rinsing mechanism comprising a rinsing tank fixedly connected to one side of the inside of the spraying box, a rinsing pipe disposed inside the rinsing tank, and a sealing component disposed inside the rinsing tank, and a conveying mechanism on one side of the spraying box, the conveying mechanism comprising a storage tank fixedly connected to one side of the spraying box, a conveying pump connected to one side of the storage tank, and a recycling component disposed on one side of the spraying box.

[0008] The present invention is further configured such that a support net is fixedly connected to the bottom of the rinsing tank, a base is fixedly connected to the top of the support net, and the rinsing pipe is fixedly connected to the inside of the base by bolts.

[0009] The present invention is further configured such that the sealing assembly includes a hydraulic cylinder movably connected inside the flushing tank via a rotating shaft, and a sealing plate movably connected to the output end of the hydraulic cylinder via a rotating shaft.

[0010] The present invention is further configured such that the water outlet end of the delivery pump is connected to a delivery pipe, and the other end of the delivery pipe is connected to the flushing pipe.

[0011] The present invention is further configured such that the recycling component includes a recycling box disposed on one side of the spray box, a first recycling pipe connected to the bottom of the rinsing box, a three-way valve connected to one end of the conveying pipe, and a second recycling pipe connected to one end of the three-way valve.

[0012] The present invention is further configured such that a support plate is fixedly connected to one side of the spray box, and a support groove is provided on the top of the support plate.

[0013] The present invention is further configured such that a replenishment pipe is connected to the top of the storage tank, a drain pipe is connected to the bottom of the storage tank, and a valve is connected to the surface of the drain pipe.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model achieves automatic in-situ cleaning of the spraying pipe through the coordinated movement of the moving component and the rinsing mechanism. After the spraying operation is completed, the moving component accurately moves the spraying pipe to the top of the rinsing tank. Then, the hydraulic cylinder of the sealing component drives the sealing plate to flip open, and the spraying pipe descends so that its pipe opening connects with the rinsing pipe. The delivery pump starts simultaneously, pumping the cleaning fluid into the rinsing pipe through the delivery pipe, forming a jet to flush the inner wall of the spraying pipe and the delivery pipe. The above method replaces the traditional inefficient manual disassembly and cleaning method, effectively improving the equipment maintenance efficiency, avoiding the pipe blockage problem caused by the solidification of paint residue, and ensuring the stability of spraying quality and the continuity of production.

[0016] 2. This utility model constructs a highly efficient closed-loop system for cleaning fluid supply and waste liquid recycling through the linkage of the conveying mechanism and the recycling component. During the rinsing process, the conveying pump stably pumps the cleaning fluid in the storage tank to the rinsing pipe. At the same time, the waste liquid generated during rinsing is collected in an orderly manner. One path flows out from the bottom of the rinsing tank through the first recycling pipe, while the other path switches the passage of the three-way valve on the conveying pipe, allowing the residual fluid in the pipe to be discharged through the second recycling pipe. The two waste liquids are finally unified and merged into the recycling tank. This not only realizes the efficient utilization of the cleaning fluid, but also ensures that the waste liquid is centrally and properly treated. It effectively solves the problems of waste liquid splashing, environmental pollution, and work site pollution in the previous cleaning process, and improves the environmental friendliness and cleanliness of the equipment.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1

[0027] Please see Figures 1-5 This utility model is an automatic spraying device for waterproof coating of outdoor labels, including a spraying box 1, a placement plate 2 at the bottom of the spraying box 1, a moving component 3 at the top of the spraying box 1, a spraying pipe 4 on one side of the moving component 3, a conveying pipe 5 connected to one side of the spraying pipe 4, a rinsing mechanism 6 on one side of the inside of the spraying box 1, the rinsing mechanism 6 including a rinsing box 61 fixedly connected to one side of the inside of the spraying box 1, a rinsing pipe 62 disposed inside the rinsing box 61, and a sealing component 63 disposed inside the rinsing box 61, and a conveying mechanism 7 on one side of the spraying box 1, the conveying mechanism 7 including a storage box 71 fixedly connected to one side of the spraying box 1, a conveying pump 72 connected to one side of the storage box 71, and a recycling component 73 disposed on one side of the spraying box 1.

[0028] Specifically, the core function of the rinsing mechanism 6 is to achieve automatic, in-situ cleaning of the spray pipe 4 to prevent paint residue from hardening. After the spraying operation is completed, the moving component 3 moves the spray pipe 4 to directly above the rinsing tank 61. Subsequently, the hydraulic cylinder 631 in the sealing component 63 actuates, driving the sealing plate 632 to flip open, opening the top of the rinsing tank 61. The rinsing pipe 62 then aligns with the opening of the spray pipe 4. The hydraulic component above the spray pipe 4 pushes the spray pipe 4 downward, causing the rinsing pipe 62 to slightly enter the spray pipe 4. The delivery pump 72 pumps the cleaning fluid into the rinsing pipe 62, and the jet directly washes the inner wall of the spray pipe 4 and the inner wall of the conveying pipe 5, effectively improving the automation level of equipment maintenance and eliminating the inefficiency and inconvenience caused by traditional manual disassembly and cleaning. Precise rinsing effectively prevents nozzle clogging, ensuring the stability of coating quality and the service life of the equipment. The function of the conveying mechanism 7 is to provide cleaning fluid for the rinsing operation and to be responsible for the subsequent recycling of waste liquid. The conveying pump 72 is started to pump the cleaning fluid in the storage tank 71 to the rinsing pipe 62 through the conveying pipe 10. The waste liquid generated by rinsing is recycled in two ways. One way flows out from the bottom of the rinsing tank 61 through the first recycling pipe 732, and the other way flows through the conveying pipe 5 and the three-way valve 733 connected to it to switch the passage and be discharged through the second recycling pipe 734. The two waste liquids finally converge into the recycling tank 731, realizing the efficient supply of cleaning fluid and the centralized and orderly recycling of waste liquid. This not only improves the continuity and efficiency of the cleaning process, but also effectively solves the environmental pollution and workshop cleaning problems caused by waste liquid splashing everywhere.

[0029] Example 2

[0030] Please see Figures 1-5Based on Embodiment 1, a support net 8 is fixedly connected to the bottom of the flushing tank 61, and a base 9 is fixedly connected to the top of the support net 8. The flushing pipe 62 is fixedly connected to the inside of the base 9 by bolts. The sealing assembly 63 includes a hydraulic cylinder 631 movably connected to the inside of the flushing tank 61 via a rotating shaft, and a sealing plate 632 movably connected to the output end of the hydraulic cylinder 631 via a rotating shaft. There are two hydraulic cylinders 631 and two sealing plates 632. One side of the sealing plate 632 is movably connected to the flushing tank 61 via a rotating shaft. The outlet end of the delivery pump 72 is connected to a delivery pipe 10, and the other end of the delivery pipe 10 is connected to the flushing pipe 62. The recovery assembly 73 includes a set of A recycling bin 731 on one side of the spraying box 1 is connected to a first recycling pipe 732 at the bottom of the rinsing box 61, a three-way valve 733 at one end of the conveying pipe 5, and a second recycling pipe 734 at one end of the three-way valve 733. The other ends of the first recycling pipe 732 and the second recycling pipe 734 extend to the top of the recycling bin 731. The surfaces of the conveying pipe 5 and the second recycling pipe 734 are connected to self-control valves. A support plate is fixedly connected to one side of the spraying box 1. A support groove is opened on the top of the support plate. The recycling bin 731 is located inside the support groove. A liquid replenishment pipe is connected to the top of the storage bin 71, and a drain pipe is connected to the bottom of the storage bin 71. A valve is connected to the surface of the drain pipe.

[0031] Specifically: The base 9 is used to fix the rinsing pipe 62 in the rinsing tank 61, so as to facilitate the replacement of different specifications of rinsing pipe 62 according to the size of the spray pipe 4, so as to ensure that the rinsing pipe 62 can be slightly inserted into the spray pipe 4 during cleaning to complete the rinsing of the spray pipe 4. The sealing component 63 is used to seal the top of the rinsing tank 61 when cleaning is not performed, so as to prevent the diffused paint from falling into the rinsing tank 61. The conveying pipe 10 is used to convey the rinsing liquid in the storage tank 71 to the rinsing pipe 62 through the conveying pump 72. The recycling component 73 is used to collect the waste liquid generated during rinsing. The support plate is used to support and limit the recycling tank 731.

[0032] The working principle of this utility model is as follows: When the operation starts, the outdoor label to be sprayed is placed on the placement plate 2 inside the spray box 1. After the equipment is started, the moving component 3 drives the spray pipe 4 to move above the label along a preset path. At the same time, the paint is pumped into the spray pipe 4 through the conveying pipe 5 and is finally evenly sprayed onto the label surface to complete the waterproof coating.

[0033] Once a batch of label spraying is completed, the automatic rinsing process is initiated. First, the moving component 3 moves the spraying pipe 4 directly above the rinsing tank 61. Then, the hydraulic cylinder 631 in the sealing component 63 actuates, driving the sealing plate 632 to flip open, exposing the rinsing pipe 62 inside the rinsing tank 61. Next, the spraying pipe 4 descends under the drive, precisely aligning its opening with the rinsing pipe 62 and slightly fitting it in. Simultaneously, the delivery pump 72 starts, pumping the cleaning fluid from the storage tank 71 into the rinsing pipe 62 through the delivery pipe 10. The powerful jet flushes the inner walls of the spraying pipe 4 and the material delivery pipe 5. The waste liquid generated during rinsing is recovered in two ways: one way flows out from the bottom of the rinsing tank 61 through the first recovery pipe 732, and the other way is through the switching of the three-way valve 733 on the material delivery pipe 5, allowing the mixture of paint and cleaning fluid remaining in the pipe to be discharged through the second recovery pipe 734. All waste liquid is finally collected in the recovery tank 731, completing the entire automatic cleaning and recovery process.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
